[PATCH] xen/riscv: copy_to_guest/copy_from_guest functionality.

From: Slavisa Petrovic This patch implements copy_to_guest/copy_from_guest functions for RISC-V. These functions are designed to facilitate data exchange between guest and hypervisor. Signed-off-by: Milan Djokic Signed-off-by: Slavisa Petrovic --- Tested on qemu with xcp-ng latest branch

[PATCH v3] x86/efi: Use generic PE/COFF structures

From: Nikola Jelic Adapted x86 efi parser and mkreloc utility to use generic PE header (efi/pe.h), instead of locally defined structures for each component. Signed-off-by: Nikola Jelic Signed-off-by: Milan Djokic --- Changes in V3: - Add xen/include among include dirs for mkreloc, instead
